Product Introduction
Light calcium carbonate—also referred to as precipitated calcium carbonate (PCC)—has calcium carbonate as its primary component, typically with a content exceeding 98%. It functions as a high-performance filler across industries including rubber, plastics, papermaking, coatings, and inks. Beyond this, it finds extensive application in organic synthesis, metallurgy, glass manufacturing, and asbestos production.
Notably, its sedimentation volume ranges from 2.4 to 2.8 mL/g. When fully dispersed, standard light calcium carbonate particles exhibit a date pit-like morphology, with a major axis of approximately 5–12 μm, a minor axis of 1–3 μm, and an average particle size of 2–3 μm.
Specification
Common sizes are 100mesh, 325 mesh, 600 mesh, 1250 mesh, We also accept customization if you need.

Product Usage
Papermaking/Coatings/Rubber/Plastics
Glass powder is a high-performance "industrial monosodium glutamate". Leveraging its properties such as high hardness, chemical inertness and low oil absorption, it can significantly enhance the mechanical properties, durability and appearance quality of products like coatings, adhesives and plastics, making it an indispensable and important functional filler in modern industry.
Premium Refined Quartz,the silicon dioxide (SiO₂) content is ≥ 99.5%, with extremely low impurity content. It has a pure white appearance and a crystal texture, as clean as white sugar, and can meet the stringent requirements of high-end scenarios for raw material purity and appearance.
Glass-based luminous stones, functional decorative materials, are produced by combining high-quality rare earth long-lasting luminous materials with glass substrates through special techniques like high-temperature sintering or melting. They inherit glass’s crystalline transparency and hard texture, and are also endowed with the magical trait of self-luminescence at night, delivering a clear, cool, and strongly modern optical effect. Their uses span garden road paving, wall guidance signs, safety warning lines, water feature design, kitchen countertops, bathroom walls, and lobby feature walls.
High-quality kaolin experiences physical and chemical transformations when calcined at high temperatures. It loses components such as fluorine through dehydration and crystallization. Once cooled, it becomes calcined kaolin—characterized by high silicon content, excellent whiteness, strong oil absorption, and great hardness. This material is widely applied in ceramics, papermaking, wall tiles, floor tiles, rubber, chemical coatings, and more.
Hollow glass microspheres are lightweight spherical particles characterized by a smooth and reflective surface. Predominantly formulated with alkali-lime borosilicate glass, they possess a distinctive set of properties: low density, high mechanical strength, low thermal conductivity, excellent electrical insulation performance, temperature resistance, chemical stability, and good fluidity. These multi-functional microspheres are extensively utilized in adhesives, corrosion-resistant coatings, insulating coatings, construction materials, rubber products, synthetic wood, oilfield cementitious materials, and lightweight automotive composite materials.
Metallic colored rock flakes for premium special effect coatings. Custom metallic effects including gold, silver, and bronze finishes. Enhanced reflectivity and depth for high-end architectural and design projects.
Yellow vermiculite is primarily sourced from the alteration of biotite or phlogopite mica in igneous and metamorphic rocks. Major deposits exist in South Africa, the US, and China, extracted via mining then processed through heating for expansion.
Hollow glass microspheres—lightweight, spherical particles with a smooth, reflective surface—are mainly made of alkali-lime borosilicate glass. They integrate unique properties: low density, high strength, low thermal conductivity, top-tier electrical insulation, temperature resistance, chemical stability, and excellent fluidity. These versatile microspheres find wide application in adhesives, corrosion-resistant & insulating coatings, construction materials, rubber, synthetic wood, oilfield cements, and lightweight automotive composites.
